SPECIFICATION forming part of Letters Patent No. 364,195, dated May 31, 1887.

Application filed March 7, 1887. Serial No, 2:39.967. (No model.)

T at whom it may concern:

Be it known that we, JAMES POLK VON STEIN and HENRY ALEXANDER WHITE, of North Liberty, in the county of Johnson and State of Iowa, have invented a new and Improved Gatc, of which the following is a full, clear, and exact description.

This invention relates to gates, the Object of lheinventi on being to provide a simple, cheap,

and durable gate, which may be opened by the occupants ofan approaching vehicle, and one wherein the parts are so constructed that snow will not be likely to interfere with their operation.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a side view ofiny improved form Of gate, the view being shown in partial longitudinal section, the gate being represented as it appears in its closed position. Fig. 2 is a side view of the gate, representing the parts as they appear when the gate is open. Fig. 3 is a view of the forward end of the gate, parts of the operating -levers being broken away; and Fig. 4 is an enlarged detail view illustrating the construction and general arrangement of the tracks or ways and the gate supporting rollers.

In constructing such a gate and supporting- .frame as are illustrated in the drawings above referred to we provide two double posts, 10 and 11, each post consisting of two properly braced and inclined standards, 2, said posts being united by an upper cross-bar, 12, which is held to place between the upper ends of the standards of each post by bolts 3.

To the rear of the post 11. we arrange a post, 13, the upper end of which is slotted to' receive a rod or bar, 14, that is pivotally mounted within the slot so formed in the upper end of the post, and between the two standards of the post 11 we pivot a second rod or bar, 15, which extends forward between the standards of the post 10 to a point slightly .beyond the forward face of said post, there to be supported by links 16, the upper ends of which are connected to levers 17, that are mounted to swing upon supporting-strips 18, which said strips are bolted to the standards of the post 10 and together form a V-shaped support for the levers 17, serving at thesame time as braces for the post in connection with which they are arranged. Although any properforln of connection could be employed between the levers 17 and their support 18, we prefer to form said levers with slots 19, through which there are passed pins or bolts 20, that engage with the-supports 18, this arrangement being clearly shown in Figs. 1 and 3.

The end of the rod or bar 14, which, as before stated, extends forward between the two standards of the post 11, is supported by a rope or chain, 21, one end of which said rope or chain is secured to the bar 14, to be carried thence upward and over asheave, 22, that is carried by the bar 15, thence along beneath the under side of the bar 15, to and over a second sheave, 23, carried by said bar, to and over a short cross-bar, 24, that is carried by the standards of the post 10., spanning the space between the two standards of the post, the end of the rope or chain 21 being secured to any proper fixed support-as, for instance, a short crossbar, 25, thatis carried by the two standards of the post 10. Within the upper faces of the bars 14 and 15 we secure metallic rails 30, the upper edges of which areV-shaped.

The parts above described constitute our gate-supporting frame, the gate itself consisting of a gate-body, 40, provided with a forward stile, 41, which extends upward beyond the cross-bar 12, the upper portion of this stile being slotted, as shown at 4, to provide for the passage of said cross-bar and for the passage of the bar 15 and its track 30, a roller, 42, being mounted in the slot 4 in such position as to ride upon the track 30, the peripheral face of the roller being grooved to correspond with the angular edge of the track, as is probably best shown in Fig. 4. By thus extending the stile 41 upward and slotting it for the crossbar 12, the pivoted bar 15 will be relieved from lateral strain when the gate is being opened during wind-storms, and the stile itself will also be supported and strengthened.

The upper end of the rear stile, 43, of the gate-body is also slotted, and the bar 14 passes through the slot so formed, a roller, 44, being mounted within the slot in position to ride upon the rail of the bar 14, this roller being similar to the roller 42, hereinbefore described.

A catch, 45, having an inclined face, 46, is carried by the stile 41, the catch being held in an extending position by alimit-pin, 47, arranged as best shown in Fig. 1, the arrangement being such that as the gate approaches the position in which it is shown in Fig. 1 the inclined face of the catch will. strike against a keeper, 48, mounted between the standards of the post 10, and as the gate continues to advance the catch will rise and eventually drop into engagement with the keeper, the forward motion of the gate being limited by a bufferblock, 49, the location of which is clearly shown in Figs. 1 and 2. On the ends of each of the levers 17 there is mounted a swinging handle, 50.

Such being the general construction of our improved gate, the operation is as follows: When it is desired to open the gate, one of the handles 50 is grasped, and the extending end of the lever 17, to which said handle is connected, is drawn down, and as the lever is so drawn down the bar 15 will be raised, so that it will incline downward toward its pivotal connection, the position of the bar being that in which it is shown in Fig. 2. As the bar 15 is so raised, the rope or chain 21 will be drawn upon and the bar 14 will be raised, so that it will also incline downward toward its pivotal connection with the post 13. After the parts have been moved as described, the gate will roll backward to clear the way between the posts 10 and 11, the parts being held in the position in which they are shown in Fig. 2, through the medium of thelevers l7 and their swinging handles, the weight of said handles being so adjusted as to slightly overbalance the weight carried by the short arms of the levers. When it is desired to close the gate, one of the levers 17 is forced upward, and the track-supporting bars are moved so that they incline downward from their pivotal connections with the posts 11 and 13. It will of course be understood that as soon as the bars have been inclined to so move downward from their pivotal connections the gate will roll to the position in which it is shown in Fig. 1.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent 1. The combination of the gate-posts and a post in rear of the inner post, and upper and lower parallel bars pivoted, respectively, at their rear ends to the inner gate-post and the post in rear thereof, a pulley on the free end end of the upper parallel bar, substantially as set forth.

2. Thecombination, with agateformed with an upwardly-extending forward stile, in the upper end of which there is formed a long vertical slot, and a shorter back stile that is also slotted, of rollers carried by the stiles, gate-posts formed of p roperly-co nnected standards, atrack that is pivotally mounted between the standards of the rear gate-post, an auxiliary post, a track pivotally connected there to, sheaves arranged in connection with the first-named track, a rope or chain connected to the second track and passing over said sheaves to a fixed point, and operating-levers connected to the forward end of the first-named track, substantially as described.

3. lhe combination, with posts 10 and 11, of agate formed with stiles 41 and 43, rollers 42 and 44, carried by the stiles, a post, 13, tracks 30, mounted upon the bars 14 and 15, that are pivotally connected to the posts 11 and 13, a rope, 21, connected to the bar 14, sheaves carried by the bar 15, over which the rope 21 passes, and levers 17, connected to the bar 15, substantially as described.

4. The combination, with posts 10, 11, and 13, of a cross-bar, 12, connecting the posts 10 and 11, track-supporting bars 14 and 15, pivotally connected to the posts 11 and 13, sheaves carried by the bar 15, a rope connected to the bar 14 and passing over said sheaves to a fixed point, levers connected to the bar 15 and counterbalanced by swinging handles, a gate formed with a long forward stile, 41, the upper end of which is formed with a slot, 4, and with a shorterrear stile, 43, also formed with a slotted upper end, and sheaves 42 and 44, carried by said stiles, the sheaves being mounted upon the tracks carried by the bars 14 and 15, all substantially as described, and for the purpose stated.
